Comment 2 for bug 1801150

Having both a "Show" and a "Visibility" checkbox there will hopelessly confuse many users (perhaps even me).

A better strategy might be a dialog like PCBNew's Edit Text and Graphics Properties where you could just whack the Datasheet fields of everything to some specified property set. It would also come in handy for global editing of text sizes and styles.

Are you sure about the bug in comment #1? I know it used to work that way, but it was fixed for 5.1 (and it's still working fine for me).
